To wil to whom. thescprescnts shall come:

Be it known that l, JGEL MOULTON, of Boston, in the county of Suffolk, and Commonwealth of Massaehusetts,'have made an invention ofa new and useful 'Process or Mode of' Covering Elastic Rolls; and do hereby declare the following to be a full, clear, and exact description thereof', due reference being had to the accompali yin g drawings, making part of this specification, and in which- Figure 1 is an elevation, and

Figure 2, a vertical-section of a machine in which the process is effected.

The invention herein described relates to means for enveloping an elastic roll in its outer case or jacket,

which is applied to it for the purpose of imparting to it'a finished appearance, and a smooth and perfect surface, a particular form of elastic roll to which my invention has special and local pertinency being those intended for clothes-wringeis, and which have heretofore been covered by hand, at considerable expenditure of time and labor.

ln carrying ont the ideas of my invention, I employ first an upright hollow cylinder or receiver, shown at c in thedrawings, for reception of the roll and its covering, and over this cylinder 1 dispose.; within a suitable frame, b, a reciprocating perpendicular plunger, e, actuatedby a rack, (l, and pinion e, the former being affixed to the inner side of the plunger, and the latter mounted upon a shaft, j', suitably supported in boxes or bearings provided for it 'at the upper part` of the frame b. L

.Rotation of the pinion e in either direction willof course produce corresponding vertical movements of the plunger c toward or away from the cylinder a'.

In pursuance of my mode of covering the roll, I insert within the cylinder a the thin elastic jacket or tube y, destined to give the finished surface to the roll, a small portion of's\1 .litnbe being left protruding from the top of the cylinder, by laying hold of which the bulk of the tube is prevented from becoming doubled or wrinkled within' said cylinder, and the act of inserting the lower end of the roll therein rendered more certain and expeditions.

'lhe tube having been inserted within the receiver.

as explained, the roll shown at h ivn the drawings is to be placed perpendicularly over the mouth of theeylinder, and its lower end inserted within the latter.

lhe Outer circumference or surface of the roll, as well as the inside of the jacket, is at this time, if not previously done, to be smeared with a suitable cement,

and the pinion-shaft rotated in the right direction, which effects a descent of the plunger, its lowerend being preferably recessed to receive. the upper end of the roll-shaft, iu order to insure a perpendicular' position ofthe latter.

The descent of' the plunger effects a correspondingr descent of the roll within the tube 11, the cement acting as a hibricator, to facilitate the entrance. of' the roll.

The plunger having been lowered to such an extent as to drive the roll into its tube to the distance required, the pinion-shaft is rotated in a reverse. direction, and the plunger removed from Contact with the. roll-shaft, and elevated to its starting-point, the -roll enveloped in its thin tube or dress, which clings tightly to it, being next removed with the receiver a, and properly vulcanized.

By the mode above described, I am enabled to accomplish the covering of. an elastic roll in much less time, and with much less labor, than the same object can be effected by means now gencrally adopted, the saving in a large establishment being a matter of' no Small importance.

U Zaini.

l claim as my invention, and desire to secure by Letters Patent of the United States- 'lhe mode of covering elastic rolls bercinbefore explained, that is to say, in first depositing the thin tubular covering or casing within the receiver a, next placing over it the roll, and smearing one or bth with een1ent,and then depressing the roll within the casing by means of' the plunger c, the whole being arranged and operating in manner as hereinbcfbre explained.

JOEL MOULTON.
